ROTARY PAPEREAND CARD CUTTlNG MACHINE.

SPECIFICATION forming part of .Letters Patent No. 247,817, dated October 4, 1881.

Application filed January 27, 1881. (No model.)

To all whom it may concern Be it known that I, HENRY P. FEISTER, a citizen of the United States, residing in the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Rotary Paper and Card Outting Machines, of which the following is a specification.

My invention relates to an improvement in that class of rotarypaper and card cutting machines in which gangs of circular cutting or shearing knives are placed adj ustably on parallel rotating shafts, (one above the other,) the edges of the upperknives being placed in close proximity to and slightly overlapping the edges of the knives on the lower shaft, and thenmade to rotate toward each other, in a cutting or shearing manner, by twin gears se cured to the ends of the parallel shafts, the paper being first fed into parallel feed-rolls in front and carried into the circular cuttingknives, and carried through them into similar and like speeded rolls in the rear of thccuttingknives, (called delivery-rolls,) and cut into long parallel strips, (called slittings,) after which these parallel strips are reversed and again passed through the knives crosswise, and cut into business or other cards suitable for market.

The accompanying drawings fully set forth my improvement, in which Figure 1 is a side elevation and part-sectional view, (one housing or side frame being removed to better illustrate the internal working parts Fig. 2, a part-sectional view of the mechanism used to actuate the feeding-fin gers, the view showing it as seen from the front of the machine Fig. 3, a perspective view of my card-receivin g racks detached from their trough. Fig. 4 shows'the trough detached from the machine, with front side removed and the card-receivingracks in position, together with cards assembled in one of the spaces, illustrating the manner in which they are delivered by the machine.

Similar letters refer to similar parts throughout the several views.

The shafts B and G, fitted with circular cutting-knives D D, are made to rotate in the housings A A in the direction shown by the arrows. Feed-rolls E, E and delivery-rolls F F revolve in the same direction, the velocity of their peripheries being made equal to that of the cutting-edges of rotating-knives D D.

The apron or table G is provided with slots H, corresponding with feed-fingers L L L L L, in which the feed -fingers L reciprocate, the fingers projecting slightly above the table G, in order to carry forward the strip W into feed-rolls E 'E. The feed-guide I extends entirely across the table G, parallel with feedrolls E E, and is slotted transversely at r',corresponding to slots H in table G, the fingers L, on their return motion, passing into slots t and remaining there while the strip W (to be cross-cut into cards) is being placed in front of them and against guide I, to be then carried forward into feed-rolls E E.

W is the pack of strips (or slittings) to be cross-cut into cards; W the strip being carried into feed-rolls E E; W, the cards out and delivered home into the receiving-racks R, W, Fig. 4, also showing the manner in which the cut cards are assembled or stacked in the receiving-racks R as they emerge from delivery-rolls F F.

On the under side of feed-table G are bolted, parallelto each other, grooved guides J J, the

grooves facing each other, and the guides set at right angles to feed-rolls E E. To these grooves are fitted semicircular tongued and .slotted arcsK K, the arcs K K being secured together by stay-rods k k k. 011 top of arcs K K are arranged adjustable finger-rod carriersL L, having longitudinal V-shaped slots 3 extending nearly their entire length, thus admitting the finger-bar g to be adjusted to suit various widths of strips in cross-cutting by simply loosening the thumb-screws M, which pass through an extension-of the tongue on arcs K K and engage with the nut l and moving the fin ger-rod carriers L L to the desired position and again fastening thumbscrew M.

19 p and p p are hangers bolted to grooved guides J J and to arms of housings A A, and in which crank-shafts P P rotate, motion bein g transmitted thereto from cutter-shaft O by belts P and pulleys on crank-shafts P P.

The roller-shaft O is fittedv with friction-rollers N N, one on each end, and is secured to and rotates with cranks O O, and imparting reciprocating motion to arcs K K, which carry finger-rod g.

For receiving the cut cards as they pass from the delivery-rolls F F,'I use the devices shown in Figs. 3 and 4, also shown in position in rear of machine, Fig. 1. These I call delivery-racks, not boxes, as those used heretofore were called. 1 construct them as follows: Awood or metallic trough is made of a length suitable for the number of racks I may desire to use. This trough consists of bottom Q and parallel side pieces, Q Q, and top guide, S, the guide S being recessed on the under side, thus forming a slot nearly its entire length to accommodate the thumb-screws S S, used for securing the tongued and slotted receiving-racks It in their several positions of adjustment, depending on the widths of cards it is desired to cut.

The receiving-racks R R are made of brass or sheet metal of any kind, (or wood will answerifmade very smooth and accurate.) They are made in shape as shown in Fig. 3, being right-angled and provided with series of parallel tongues 1' and slots 1', extending to within one inch of their apex, the ends of the slots terminating parallel with said apex. These parallel tongues r are made to correspond with similar parallel slots, 1', on the next adjoining rack R, and to interchange with and adjust with each other until as many racks are placed in thetrough as it may be desired to use, they being placed in the trough with the tongues downward, as shown in Fig. 4, and secured in their requisite positions by thumb-screws s, as before stated.

The top surfaces of all the racks It, when placed in the trough, as shown in Fig. 4, will then stand at an angle of forty-five degrees with each other. This will cause the cards to assemble in the racks R, as shown at W*, Fig. 4, with their edges in parallel. vertical lines, leaving spaces between each pair of packs to facilitate their removal from the racks B. When full the receiving-racks above referred to are placed as shown in Fig. 1, the apex of each rack being placed in line with each alternate pair of rotating cutting-knives D D, the apex of each rack serving to separate each alternate cut made by the cutting-blades D D as the cards drop from the delivery-rolls F F, and thus separate themselves by contact with apex of racks It, thus causing two packs of cards to assemble between each pair of the racks R, as shown at V Fig. 4.

It will be seen, also, on reference to the drawings, Figs. 3 or 4, that the racks B may be adjusted to different positions in the trough Q, and to suit various widths of cut, their angles still remaining the sameviz., forty-five degrees-thus maintaining the very desirable feature of assembling the cards on the racks R with their edges vertical, as shown at \V, Fig. 4.

On the under side of inclined table V are brackets V and on the top are secured ratchet-plates U, provided with joints or pivots q and t and pawl T, this device being used to raise the rear side of the trough, containing racks R, to different angles, it being sometimes necessary to do so, some classes of cards having more velocity as they emerge from rollsF F than others, chiefly owing to the difference in weight of the card-stock.

The operation of my invention is as follows:

Arotary motion isim parted to the crankshafts P P by cutter-shaft 0 through belts P (two being used, but only one shown,) thus giving a reciprocating motion to the semicircular slotted arcs K K, by means of cranks O O, roller-shaft O, and friction-rollers N N, rotating in the semicircular slots, the finger-bar carriers L L also partaking of the same motion by being mounted on top and moving with reciprocating arcs K K, the arcs K K being guided in their lIlO"Gll1Clli] by grooved guides J J.

I is the teed-guide, E E the feed-rolls, L L L L L the feeding-fingers, and V the pack of strips about to be cut into cards. The feeding-fingers L are caused to remain at rest during about. half a revolution of the crankshaftsP, or while theyare rcvolvingin the slotted arcs K K concentrically, the fingers remaining during this time under the guide I in slots 1'. This is a very desirable feature, as the temporary stoppage and rest of fingers L under guide I affords the operator ample time to carefully lay and adjust the strip in front of guide I previously to its being carried forward to the feed-rolls E E by fingers L. It also enables the machine to be run at a much greater speed than heretofore, and still give ample time for properly feeding it.

My feeding mechanism also guarantees a better delivery of the cut cards into its receivingracks It, as the more accurate thestrips are carried to the feed-rolls the more uniform will be the delivery of the cut cards, the rest or stoppage of the feeding-fingers under guide 1 always permitting the operator to carefully adjust the strip and insure its parallel entry into feed-rolls E E.

In cutting cards, the strips (or slittings) are placed on the feed-table, as at NV, and then in front of the fingers L, and carried into the feed-rolls, as at W, and through the rotating knives D D and delivery-rolls F F, as at W then delivered and assembled in receiving racks It, as at W*.

Having fully described my invention, 1 claim as new 1. In a rotary paper or card cutting machine, semicircular tongued and slotted arcs. K K, in combination with the adjustable finger-bar carriers L L, having longitudinal V- shaped slots 3 1 and thumb-screws M, substantially as shown and described.
